I am planning on a two node cluster with multiple instances. I will have two databases and two separate applications will be going against them. I want 'APP 1' to go against 'DB 1' on 'NODE 1' and failover to 'NODE 2'. I want 'APP 2' to go against 'DB 2' on 'NODE 2' and failover to 'NODE 1'. Is this possible? Does that mean that I will have two virtual servers? Yes, and Yes. |

Will I have one default instance and one named instance on each node? You choose. I prefer to make all clustered instances of SQL named |

I prefer to make all clustered instances of SQL named instances. The instances are per cluster, not per node so you can only have one default instance on a cluster. Each instance can live on one host node at any given moment. You can choose the failover order. The outside world sees each instance as a named instance of a SQL server. |

Hi Geoff, Let me get this right. It is impossible to have an active/passive cluster with, for example, 16 virtual servers without naming the instance on each one of them, except one (the default). Is that right ? thank you "Geoff N. Hiten" <SRDBA (AT) Careerbuilder (DOT) com> wrote Comments Inline -- Geoff N.
